Troubleshooting Vox AC4TV8 help.

Hey guys, I've got a little dilemma here, my Vox AC4TV8 suddenly stopped working. I was just playing at practice when suddenly it went silent. No sound, LED still ON, just a little faint hum.

I turned it off for 30 minutes and turned it on again, there was a LITTLE sound at first then 3-5 seconds later it went out again like turning down the volume but really fast. tried it again a couple of hours later, no more sound not even a little except for that really FAINT hum and the led indicator still ON.

I changed the tube, same problem. The fuse doesn't seem to be blown, if they're blown the led indicator wouldn't go ON right?(if I'm getting this right)

I'm in Japan and the closest Amp tech is like 400 Kilometers away so I'd rather try and fix this myself if I can.

I had a similar problem with my AC4. After researching the amp on line I found they had a run of amps with bad diodes (rectifier).
Probably best to pull the chassis (it's light) and mail it to the tech telling him about the diodes.
Good luck.

Someone on another forum pointed out about the Fuse, it looked normal so I didn't really check it. Upon checking, I found out that FS2 Fuse is not working. I checked it with a multimeter and it's not registering anything.

It is labeled as 160mA 250v which seems kinda weird because upon my research everyone seems to find a 125mA. I can't even find a 160mA in my usual online stores. I'll just get a 125mA to try it out and some new tubes.

Best case scenario it's just the fuse, otherwise I'm checking out the diodes.
